Mavenir specializes in software aimed at taking better advantage of LTE and WiFi for voice connections. VoLTE has been a long time in coming, but seems to be just about ready to come into its own. Mitel will be integrating Mavenir's technology and capabilities into their own UC portfolio.

Mitel will be paying $560M, with which it is buying some $140M in annualized revenue and $1.00 per share in net losses. That's no so bad given the fact that their main focus of VoLTE has yet to really take off, and that potential is what Mitel is paying for.

Mitel has been very acquisitive lately, rolling up assets in the business VoIP and UC worlds. Just over a year ago, they closed the purchase of Aastra, bringing their own revenue base over $1B. They then acquired contact-center specialist OAISYS last spring as well, and made that unsuccessful attempt to acquire ShoreTel in October/November.
